Nasdaq and Brave New Coin has partnered to offer BLX, Bitcoin Liquid Index, and ELX, Ethereal Liquid Index. The indices will be quoted in US Dollars and will be based on the most liquid ends of their respective markets. Both indices will work in real time with a frequency of 30 seconds.BLX and ELX are designed to provide markets with a real time spot or reference rate for the price of one unit of Bitcoin and one unit of Ethereum respectively. "Both indices are calculated using a methodology that has been independently audited against key IOSCO principles," the press release says. "The BLX is one of the most widely-referenced BTC indices among crypto traders and has been calculated back to 2010. Likewise, the ELX has been calculated back to 2014." Nasdaq is planning to launch indices on Monday, February 25, 2019. In addition, Nasdaq will support an Equities Summary to be shared at the end of the United States and European Trading Session, as a piece of information of the activity for the current day; and the Index Directory, that will be published at the beginning of each day to share necessary index information.
